Coal dust - WikipediaDeze pagina vertalen

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.
